Body rather elongate, cover(>d witli deciduous cycloid scales of 

 moderate size ; gill-oi)enings rather Avidc. Cleft of the nioxith very 

 wide ; jaAvs with a scries of long- teeth, and with strong canine teeth ; 

 the upper jaw with a second series, which is formed hy the canine 

 teeth. Two dorsal fins, the first composed of five spines. Ventral fins 

 united, not adherent to the belly. Pseudobranchia). Vcrtebric 1 1/1 6. 



Coasts of Scotland. 



This genus is much more closely allied to Apocryptes than to 

 Gohhts, its dentition differing fiom that of the former only in the 

 arrangement of the canine teeth. The form of the teeth of the 

 outer series is exactly that which Ave observe in Apocryptes ; but 

 there is a second short series behind it, formed by tAvo groups of 

 strong and curved canine teeth, each group, occupying the front 

 part of the intermaxillary. The teeth of the Ioavct jaw are sub- 

 horizontal ; a strong, curved canine tooth is placed interiorly to the 

 end of the series of outer teeth. 



Apocryptes hrachyptcrns, Block., appears to have more affinity 

 to this genus than to the typical species of Apocryptes.
